A Novel Approach to High Dynamic Range Imaging with CMOS‐SPADs
09:50 - 10:10
Majid Zarghami, Leonardo Gasparini, Matteo Perenzoni and Lucio Pancheri High Dynamic Range (HDR) operation is required for applications such as automotive to cover a large variation of illumination intensity. The capability to count single photons up to 100’s Mphotons/s enabled Single Photon Avalanche Diodes (SPADs) to achieve a HDR. This work exploits the excellent timing resolution of SPADs to extend the dynamic range beyond the saturation level by extracting the intensity of light from the photon interarrival times, reaching 138.7-dB dynamic range within 30-ms integration time.
